Official photo of the Nokia Asha 500 leaks ahead of announcement

The first official photo of the Nokia Asha 500 has just surfaced courtesy of evleaks. The leak doesn't provide more information of the upcoming Asha 500 other than the photo itself, so no specifications are available at this point.

The phone is obviously merely a Dual SIM version of the Nokia Asha 501. We notice however some changes, which Nokia has made in the design department of the phone. The form factor seems to be left intact, but as the photo shows, there's an interesting translucent effect around the outer edges of the Asha 500. This might very well be a case, but it certainly looks cool in the photo.

Another apparent change is the Asha 500's capacitive button, which replaces the physical one in the old Asha 501. The leaked photo also confirms the Asha 500 is going to be available in a dual SIM variant as well. Additionally, the leaked press shot confirms that the Asha 500 will indeed support the popular WhatsApp messaging service.

Again, no more information about the hardware or software is available now. Nokia is holding a press event on October 22 and the Asha 500 might as well be unveiled then in addition to the highly anticipated Lumia 1520.
